I have a spider stuck inside me. He's building a spider web to protect me from the evil I put into my body. But the spider, like all creatures, needs to eat and he's eating the one precious irreplaceable part of my body (although, there is new evidence that doctors can now replace it. How interesting.). He likes it because it's sweet, the chemicals give him a headrush like no other. If he eats enough of it he passes out from the burst of adrenaline and human love. He's addicted.
